A process data transmitter transmits current process data at defined recurring intervals of time in the form of a serial transmission data stream (66) having a multiplicity of data symbols (68) at a defined symbol rate. A process data receiver samples the serial transmission data stream (66) at a sampling rate which is higher than the symbol rate by a defined factor in order to generate a serial receiver data stream (70) having a multiplicity of samples (72) for each data symbol (68). The process data receiver divides the serial receiver data stream (70) into data packets (86), each of which has a defined first number of samples (72). The process data receiver selects a defined second number of samples (72') from the respective data packets (86). The second number is smaller than the first number by the defined factor and the samples (72') selected from each data packet (86) are equidistant to one another. The process data receiver processes the selected samples (72') as received process data. |
